Knowledge for the trades
E-invoicing, GoBD and accounting — explained briefly, without legalese. Checked against our country registry.
Germany's e-invoicing mandate: the timeline
Since 2025, B2B businesses must be able to receive e-invoices — sending becomes mandatory by 2028. What applies to your business, and when.
XRechnung vs. ZUGFeRD: the difference
Both are compliant e-invoices — but built for different recipients. When you need which format.
GoBD for tradespeople: the basics
Sequential numbers, immutability, retention — what the tax office expects from your invoices.
E-invoicing in Europe: the overview
Italy, France, Peppol & co. — every country has its own formats and deadlines. Here's how to keep track.
Google reviews for trade businesses: win more jobs with real reviews
The business with good Google reviews gets the call — not the cheapest one. How to collect real reviews systematically: at the right moment, legally safe, without begging.
Maintenance contracts in the trades: predictable revenue instead of order gaps
Sold once, revenue every year: maintenance contracts smooth your order book, retain customers and fill the slow months. How to build them — from pricing to the reminder.
Proof of work & acceptance: how to avoid disputes over money
Most invoice disputes are not created at the invoice — they start weeks earlier: unclear scope, no records, no acceptance. Five habits that make sure you get paid for what you did.
Following up on quotes: how to win jobs that were almost gone
Most quotes do not die from the price — they die from silence. Friendly follow-up wins jobs that would otherwise end up with the competitor or in a drawer — systematic, without being pushy.
Working with your accountant: no more shoebox
Queries cost fees: collect receipts digitally and hand over bookings as a DATEV export, and you save money and nerves — and get your reports back faster.
Quotes that sell: variants, optional items, an easy yes
Of three quotes, the cheapest rarely wins — the clearest does. How variants, optional items and an easy acceptance win you more jobs without cutting your price.
Getting paid faster: due dates, early-payment discounts and systematic reminders
Weeks often pass between sending the invoice and seeing the money — needlessly. How clear due dates, discounts, progress payments and friendly consistency protect your liquidity.
Customer communication in the trades: appointment, arrival, handover
Customers judge your work — but they experience your communication. Five moments where a short message impresses more than perfect tools: from the enquiry to after the handover.
